What is a computer keyboard (What is the keyboard in Hindi)

What is the key in Hindi?

The keyboard is a very important part of the computer. This is an input device. It is mainly used to enter commands, text, numeric data and other types of data on the computer. Use the keyboard and mouse to interact with a user’s computer.

After this, the entered data is converted into the machine’s language so that the CPU can understand the data and instructions that come from the input devices.

How to connect the keyboard to the computer

If we talk about the first time, we used a PS / 2 or serial connector to connect the keyboard to the computer. But if I talk about that now, the USB (universal serial bus) and wireless connectors are used.

Connecting them has become very easy now. The disadvantage of Wireless Keyboard is that we have to change the battery frequently. Otherwise, it is more portable than other keyboards.

Keyboard types in Hindi

There are many different types of keyboard designs that are manufactured according to region and language.

QWERTY: This design is used in most of the world and has been named according to the 6 letters above, which you can see in the previous row above. It is often used in most countries. It is used so much that many people think that this type of keyboard is Mehsud.

AZERTY: It has been developed in France, the QWERTY design according to another variation and is also considered a standard French keyboard.

DVORAK: This design is designed to reduce the movement of the fingers so that it can be faster and faster than the QWERTY and AZERTY keyboard.

If I talk about it now, the keyboard that is used nowadays is mostly ‘QWERTY‘.

The keyboard of a computer is kept in the form of many letters, numbers, symbols, and buttons of command, and the right of these belongs to a particular category. So, if you get to know which category is the key, you can easily learn about its function.

Some keys are special keys, but they are not in some, but all keyboards have the same alphanumeric keys.

Alphanumeric keys

All keyboards have a set of keys that are called alphanumeric keys. The term “alphanumeric” means either letters or numbers, but not symbols or command keys. These numeric keys remain indistinguishable in two different parts of the keyboard:

One of these letters above and the other of these letters are correct and the other. These numeric keys that appear above the letters are double symbols. If you press the Shift button and hold down the number, what you type on that number key will be written. In the upper row of the keyboard, there are letters like “Q, W, E, R, T, and Y”. That’s why keyboards hidden in cell phones are called QWERTY keyboards.

Scoring keys

Scoring keys are referred to as those that relate to punctuation marks. For example, “comma key”, “question mark key”, “two-point key” and “period key”. These keys are all on the right side of the letter keys. Like the number keys, if you hold down the punctuation key and press Shift, you can use the second function.

Navigation keys

On the keyboard, the navigation keys are visible between the letter keys and the number keys. The navigation keys consist mainly of four arrows: up, down right and left These keys to move the cursor like a mouse on the display screen. With this, you can use these navigation keys to navigate to the website’s history.

Command keys and special keys

The command keys are called keys that give the command such as “delete”, “return” and “enter”. It depends on your keyboard, whether or not there are special keys on it. For example, to lower the volume upwards, to move videos forward and backward. The other keys are “shift key”, “shift key” and “tab key”.
